The Blayson Group Ltd
  • The process uses metal moulds to produce expendable wax based patterns of the part to be cast
  • The part can be extremely complex and may incorporate cavities
  • The patterns are mounted and coated with a ceramic material by building up layers of sand and liquid binder until a suitable shell is formed
  • The wax is removed from the shell using high pressure steam
  • The shell is fired in a furnace to 1000°C resulting in a precision mould into which the molten metal can be poured
  • After cooling, the mould is broken open and the casting is removed and is then finished
